3. A rod-shaped MgO specimen with round cross section is tested with the three-point bend method. What is the calculated minimum radius without fracture if the applied load is 5560 N, the flexural strength is 105 MPa, and the separation between the two support pins is 45 mm?
A tensile-testing apparatus is to be constructed that must withstand a maximum load of 293516 N. The design calls for two cylindrical support posts, each of which is to support half of the maximum load. Furthermore, plain-carbon(1045) steel ground and polished shafting rounds are to be used; the minimum yield and tensile strengths of this alloy are 343 MPa and 565 MPa(82,000 psi), respectively. Specify a suitable diameter in mm for these support posts. Assume safety level is 2.3. Round your answer to 2 significant figures.
